TELEPHONE SIGNALING FOR RAILWAYS.

Specification of Letters Patent.

Patented Feb. 3,1914."

Application filed August 28, 1913. Serial No. 787,218.

To all whom it may concern Be it known that I, MIKE LUTENBERGER, asubJect of the King of Hungary, residing at Blocton, in the county ofBible and State or transmitted.

Another object of this invention is to provide a telephonic hood or capthat can be easily placed upon the head and closed to exclude noise,whereby the receivers and transmitter can be used without any danger ofsuffocation during the using of the hood.

A further object of this invention is to accomplish the above results bya mechanical construction, that is simple, durable, inexpensive to-manufacture and highly efficient for the purposes for which it isintended. 1

With the above and other objects in view the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

- Reference will now be had to the drawings, wherein Figure 1 is a sideelevation of the hood, Fig. 2 is a front elevation of the same, Fig. 3is a longitudinal sectional View of the hood.

Suspended or suitably mounted within the cab of the locomotive is a hoodor cap 10 (see Figs. 1, 2 and 3.) The hood or cap is made'of leather orother flexible material and the sides thereof have receivers 11 con--nected by wire conduits 12 to a slngle cable 1 13. The front of the hoodor cap has a transmitter 14 and at one side of the cap 1s Copies of thispatent may be obtained for a ventilating opening 15 having a valvularmember 16 for controlling the admission and exhaust of air to and fromthe hood or cap. The inner walls of the hood or cap have an expansionband 17 forming a compartment 18 and this compartment can be inflatedthrough the medium of a bulb 19. By forcing air, into the compartment 18the band 17 is expanded to friction'ally grip the neck or lower part ofthe head to exclude noise from the hood or cap. The band 17 can be madeof rubber or other expansiblc material. The wire conduits 12 areprovided with tabs 20 which can be held to assist in retaining the hoodor cap upon the head.

It is thought that the utility of the telephonic hood will be apparentwithout fur ther description and while in the drawings there isillustrated a preferred embodiment of the invention, it is to beunderstood ,that

the structural elements are susceptible to such varlations andmodlficatlons asl'l-fall within the scope of the appended cl aims. WhatI claim is g 1, In a telephone signaling system for railways, alocomotive equipment compris ing a hood adapted to be placed upon thehead, receivers carried by the side thereof, a transmitter carried bythe front side of said hood, and an extensible band arranged in saidhood for excluding noise from said hood.

2. In a telephone signaling system for railways, a locomotive equipmentcompris-.

ing a hood adapted to be placed upon the head, receivers carried by theside thereof, a transmitter carried by the front side of said hood, anextensible band arranged in said hood for excluding noise fromsaid hood,means for ventilating said hood,'and means carried by said hood forinflating said band. I

In testimony whereof I aflix mysignature in the presence of twowitnesses.
